WRENCH.

SPECIFICATION forming part of Letters Patent No. 613,153, dated October 25, 1898. i

Application filed January 19, 1898. Serial No. 667,167. (No model.)

To @ZZ whom t may concern.-

Be it known that I, JOHN J. KENNELLY, of New York, borough of Manhattan, county of New York, in the State of New York, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

My invention relates to an improvement in ratchet-wrenches which are provided with a rotatable barrel having a socket formed therein adapted to engage the nut; and it consists of an auxiliary or/,removable socket -piece which is held in place by the friction of a spring-pressed block and is provided with a socket adapted to receive a nut ofa different size from the socket in the barrel of the wrench proper.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is aperspective viewof a wrench of this character with the removable socketpiece; lying alongside. Fig. 2 is an enlarged longitudinal section taken th rough the socket end of the wrench with the removable socketpiece in place. Fig. 3 is a similar view showing a socket-piece in place, having a socket adapted to receive a nut of larger diameter than the barrel of the wrench; and Fig. 4 is an end view-of the removable socket-piece.

The object of my invention isto providea removable device which may be readily attached to a socket-wrench of this character and which will enable it to engage nuts of different diameters.

The particular construction of the wrench proper is not material and has not therefore been illustrated in great detail.

The wrench, as shown, comprises a handle A and a barrel B, journaled in one end thereof and rotatable b v a suitable means mounted upon the handle. This means not forming an essential part of the present invention is not described in full.

The barrel B, as shown in the drawings, has sockets C in each end thereof fitted to engage a nut of a certain size. These two sockets are connected with each other `by a central aperture D,which ordinarily would be formed, as shown, of a circular cross-section. This circular cross-section is not, however, an essential feature, but is only 'a convenient and cheap form of manufacture. It maybe made of any cross-section desired.

The auxiliary socket-piece or reducer, as it might be termed, consists of a stem or shank E, adapted to iit the central connecting-aperture D in the barrel, provided at one end with a head F, adapted to .iit the socket C in the end of the barrel. This end of the auxiliary socket-piece or reducer is also provided with a socket f, tted to receive a nut of a different diameter from that engaged by the socket C with the barrel B. As shown in Fig. 2, this socket f is of smaller diameter than the socket in the barrel, while, as shown in Fig. 3, the head F is projected beyond the end of the barrel and the socket f therein is of larger diameter than the socket in the end ofthe barrel. Either or both of these constructions will be provided in dilferent socket-pieces adapted to be inserted in the same wrench.

To hold the socket-piece in place in the barrel, the shank or stein E is provided with a slot adapted to receive the spring-held friction-block G. This block is preferably pivoted in this slot and is provided with a tailpiece g, adapted to engage the end of the shank and prevent the block from being swung outward too far. The outer surface of the block is curved, as shown, so that the end thereof will be certain of entering the central aperture D in the barrel. It is held outward by means of a spring H, which is insex-ted in a transverse recess formed in the shank E. This spring engages the underside of the block G and holds the same out with force sufficient to hold the socket-piece in place and prevent its dropping out of the barrel in whatever position the wrench is placed. These socket-pieces are easily` inserted and removed from the wrench and will enable the wrench to be used upon nuts of different diameters instead of their use being confined to nuts of one diameter only.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An attachment for socketwrenches, comprising a removable socket-piece having a central stem provided with a slot at the outer end thereof, a spring-held frictionblock pivoted in said slot having an arrnextending over and engaging the outer end of said stern, the body thereof being adapted to project from the side of the slot and to engage the surface of the Wrench-socket to hold the attachment in place, and a head fitting the nut-socket and heid thereby against turning and having a nut-receiving cavity or socket therein of different size from the one in the Wrench, substantially as described.

2. A socket-Wrench having a rotatable barrel provided With a nut-socket and a central aperture, and means for receiving said barrel, an auxiliary socket-piece comprising a stem adapted to fit the central aperture, and
